When the pot lid is covered in the cooker body, in the case of the fan work, outer gas stream is via the wind Fan suction, the louver is sent into via wind-guiding baffle plate, finally via the support member, the vent grooves, the air-flow At the top of passage, ventilation member discharge IH electric cookers;
Wherein, the fan, the electromagnetic induction coil, the temperature sensor independently with the microprocessor control Molding block electrically connects.
Further, the ventilation member is a mutually isolated two chambers, and top surface offers use on one chamber Passage outside connection, and offer the through hole for connecting the gas channel in its side;Pushed up on another chamber Face offers the passage for connecting outside, and protrudes the part of the thermal insulation layer at it and offer for connecting the inner bag The steam vent of chamber;Preferably, the passage is arc passage.
Preferably, the support member is more than 2 blocks by uniformly being opened up along the accommodating chamber side wall top edge Composition either opens up the cylindrical sidewall of hole.
Preferably, in order to obtain preferably wind guide and heat dispersion effect, the wind-guiding baffle plate is using its geometric center as basic point direction The fan curving, and offer circular and/or the air vent of rhombus and/or ellipse, the vent area and account for this Baffle plate area 90-95%.
Preferably, in order to which the fan can be consolidated on the air deflector being arranged on below the fan, the ventilation Baffle plate is perpendicular to the plane air deflector of the cooker body central shaft, and offers the logical of circular and/or rhombus and/or ellipse Air holes, the vent area account for air deflector area 90-95%;Further, the fan leads to installed in the plane The geometric center of windshield plate.
A kind of cooling temperature control method of IH electric cookers is as follows:
S1:Switch on power, press button of cooking, micro processor controls module enters mode of operation of cooking, the electric cooker Inner bag temperature rises, and starts to cook, liquid boiling water, and temperature is maintained at boiling temperature, and moisture is reduced, until loseing liquid water, electric meal Stew inner bag chamber temp to rise, the temperature sensor sensing inner bag chamber temp reaches the fixed temperature of required cooling temperature control Line;
S2:Micro processor controls module enters standy operation mode, and at the same time, the fan is started working, outside gas Flow through and sucked by the fan, then the louver is sent into via the wind-guiding baffle plate, finally via the support member, described Vent grooves, the gas channel, ventilation member discharge IH electric cookers top;
S3:Temperature drops to the critical lower limit temperature of insulation that the electric cooker is set, and micro processor controls module, which enters, protects Warm mode of operation:The fan is stopped, and the electromagnetic induction coil accesses low-power alternating current, the temperature sensor Judge whether temperature reaches insulation critical upper limit temperature;
S4:Reach set insulation critical upper limit temperature when temperature rises, the electric cooker repeats the above steps S2, Zhi Daowen Degree drops to the critical lower limit temperature of insulation, and now, micro processor controls module enters heat insulation work pattern.
Using technical solution of the present invention, have the advantages that:
1. the IH rice cooker structures are reasonably distributed, easy cleaning, inner ventilation good heat dissipation.
2. the fan and gas channel of the IH electric cookers, can effective fast cooling.In addition, by means of microelectronic element, Intelligent precisely cooling temperature control can be achieved.On the one hand, different be heated is controlled according to the heat demand of rice each heating period Temperature, realize scientific and normalization cooking rice so that rice mouthfeel is delicious, and nutritional ingredient is abundant;On the other hand, in electric cooker In the different operating stage, different internal temperatures is controlled, be advantageous to saving and each component of electric cooker and can be protected, reduce failure Incidence.
